Hearing loss is an infrequently-reported consequence of recreational drug abuse. Although there are sporadic reports of hearing loss from heroin and cocaine ingested separately, there are no reports of hearing loss resulting from the combination of both drugs ingested simultaneously in the form of speedballing.
The purpose of this report is to document a case of bilateral sensorineural hearing loss associated with an episode of speedballing.
Case Report.
The subject of this report was a 40-year-old man with a 20-year history of substance abuse. Data collected included a case history, pure tone audiometry, tympanometry and acoustic reflexes, and transient evoked otoacoustic emissions.
The audiologic evaluation indicated a mild to moderate, relatively flat, bilateral sensorineural hearing loss that was worse in the right ear.
A bilateral sensorineural hearing loss involving both cochlear and neural pathology may be a rare complication of cocaine, heroin, or the combination of the two drugs.
听力损失是娱乐性药物滥用较少被报道的后果。虽然有零星报道分别因摄入海洛因和可卡因导致听力损失，但尚无关于以速球方式同时摄入这两种药物导致听力损失的报道。
本报告旨在记录一例与速球使用相关的双侧感音神经性听力损失病例。
病例报告。
本报告的研究对象是一名有20年药物滥用史的40岁男性。收集的数据包括病例史、纯音听力测定、鼓室图和声反射以及瞬态诱发耳声发射。
听力评估显示为轻度至中度、相对平坦的双侧感音神经性听力损失，右耳更严重。
涉及耳蜗和神经病变的双侧感音神经性听力损失可能是可卡因、海洛因或这两种药物联合使用的罕见并发症。
